摘要： Double-spot welding machine for producing wire grids (G), having welding lines (S.sub.1, S.sub.2) of top and bottom electrodes (2, 3), which welding lines (S.sub.1, S.sub.2) are arranged at a mutual distance apart in a longitudinal wire advance direction and run transversely to the longitudinal-wire advance direction. A cross-wire feed apparatus (9) feeds two cross wires (Q.sub.1, Q.sub.2) along two insertion lines (E.sub.1, E.sub.2) arranged in front of the welding lines (S.sub.1, S.sub.2) at their predetermined distance from one another. A cross-wire transfer apparatus (10) transfers the cross wires (Q.sub.1, Q.sub.2) from the insertion lines (E.sub.1, E.sub.2) into the welding lines (S.sub.1, S.sub.2). The longitudinal wires (L) are advanced to the welding lines (S.sub.1, S.sub.2) and the welded wire grid (G) is pushed out of the welding lines (S.sub.1, S.sub.2). A holding arrangement (15, 18) holds the cross wires (Q.sub.1, Q.sub.2) in interengaged position in recesses (13) on support arms (12) which are displaceable relative to the longitudinal wires (L) during the transfer from the insertion lines (E.sub.1, E.sub.2) into the welding lines (S.sub.1, S.sub.2). A control device (C) controls raising and lowering of one electrode row per welding line (S.sub.1, S.sub.2) in cycles, as well as feeding, transfer and advance devices for the longitudinal and cross wires, in synchronism, but not necessarily at the same speeds, or time intervals.

摘要： A convertible single or double spot welding machine operating by the electrical resistance method for producing grids or bar grates by single spot welding or double spot welding, has a transverse row of electrodes and at least one welding transformer on one side of the welding plane. Electrically conductive connections, which pass through the welding plane, connect the welding transformer to the electrodes located on the other side of the welding plane and close the welding current circuit for single spot welding. In order to convert from single spot welding to double spot welding, the connections which pass through the welding plane are removed, selected electrodes on the side of the welding plane remote from the welding transformer are connected in pairs by current bridges, and the supply lines from the welding transformer are respectively connected to the two electrodes opposite the electrodes connected by the current bridges.

摘要： Apparatus for the feeding of transverse wires from a feed position to the welding line of a grid welding machine has at least one nozzle (9) which is directed towards the welding line, and which can be supplied with compressed air in time with the welding cycle. Parallel guides (5, 6) lead out from the nozzle, bounding either side of the transverse wire feed path, but ending ahead of the region of the welding electrodes. There are provided, in the region of the welding electrodes (1, 2), devices (11) preferably designed as magnets, for the catching and holding of the respectively fed transverse wire at the welding line. Conveyance with compressed air means that mechanical parts engaging in the welding area and susceptible to faults are avoided and at the same time changing of the longitudinal pitch of the transverse wires is facilitated.

摘要： The invention relates to electrical multi-spot resistance welding machine for the production of welded bar gratings produced by welding cross-bars into the narrow side of parallel, upright flat bars. Such a machine has a pressure-beam which is guided vertically on a frame for lowering onto and raising away from the bars to be welded. Two rows of electrodes are disposed on the pressure beam, the rows being transverse to the feed path of the flat bars and the electrodes in the two rows being aligned in the feed direction of the flat bars and the electrodes of each aligned pair thus formed are connected to the secondary terminals of opposite polarity of a respective welding transformer. The electrodes are mounted in the pressure beam such that the electrodes of each pair aligned in the feed direction of the flat bars, are at least partially independently slidable vertically within the beam against a biasing force, the pressure beam and the welding transformers being mounted in a single unit for lowering and raising together. Short flexible supply leads connect the electrodes with the transformers.

摘要： In a grid welding machine with a horizontal longitudinal wire guide path (4) and transverse wire feeders (27, 28) arranged above and below the latter and transverse rows of active welding electrodes (7, 8), the two rows of electrodes (7, 8) are moved up or down away from the longitudinal wire path (B--B) in synchronization with the welding cycle before transverse wires (Q1, Q2) are placed simultaneously on each side of the longitudinal wire assemblage (L). The transverse wires (Q1, Q2) are then brought into the welding position between the two rows of electrodes (7, 8) and the electrodes are applied to these transverse wires (Q1, Q2). Finally, a row of electrodes (7) are stopped as an abutment against which the welding pressure is applied through the other row of electrodes (8) so that a welding current flows between each electrode pair (7, 8) in series over the point of intersection of each longitudinal wire (L) with two contacting transverse wires (Q1, Q2).

摘要： A multispot grid-welding machine has an electrode-carrier beam movable up and down and a plurality of guide rods mounting a plurality of electrode units for movement on the beam. Pressure springs bias the electrode units in a direction towards the grid being welded, each electrode unit being movable into a working position and a rest position in which it is retracted. A plurality of return springs act on the electrode units, the return springs being considerably weaker than the pressure springs and acting to shift the respective electrode units on the working position into the retracted position. Devices are provided for advancing selected electrode units into the working position by overcoming the force of the return springs.
